TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN W. HADFIELD, of Ncwtown, in the county of Queens, and State of New York, have invented a new and useful Improvement in Sky-Rockets; and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from all others of a similar class, together with such parts as I claim, and desire to have secured to me by Letters Patent.

This invention relates to a modification of an improvement in sky-rockets, for which Letters Patent were granted to me, hearing date November 28, 1865.

The original improvement consisted in a novel application of wings to the body or .carcass" of the rocket, whereby the use of the ordinary guide-stick was rendered unnecessary, and the. rockets rendered capable of being packed for transportation much more compactly than when provided with sticks. The present improvement also consists in a novel manner of attaching the wings to the body or, carcass of the rocket, whereby the same advantage is obtained as hitherto, at a less cost of manufacture. In the accompanying sheet of drawings Figures and 2 are side views of my improvement.

Figures 3 and 4, end views of figs. 1 and 2 respectively.

Similar letters of reference indicate like parts.

A represents the body or carcass of a rocket, of usual construction, and B, fig. 1, is a band or collar, constructed of sheet metal. Tin plate will probably be used. In fig. 1, the band or collar is fitted snugly or tightly on the body of the rocket, as it is not necessary to remove it therefrom, and it has tube, a, attached to or framed with it for the rod to pass through and serve as a guide when the rocket is fired. This rod is precisely the same as that shown in the original Letters Patent, and therefore does not require any explanation.

The band or collar Bis formed with projecting portions 6, to serve as loops to receive the ends of wings C,

which are constructed of'shect metal tin plate, like the band or collar B. The loops 6 may be formed by swaging or otherwise, and it is not necessary that they extend the whole height of or entirely across the band or collar, but be about the length as shown in fig. l. The wings C have their inner edges, 0, bent, to form lips or flanges, at right angles with their main portions, and the upper end of each wing is slitted longitudinally at the angle of the lipsor flanges and the bodies of the wings, as shown at d, so that the upper ends of the wings or flanges may-be fitted in the loops 6, as will be fully understood by referring to fig. 1.

By this arrangement it will be seen that the wings C maybe applied to and detached from the band or collar with the greatest facility, and when the rockets are packed for shipment the wings are not applied to the rockets, but enclosed in a package or by themselves, or they may be adjusted flatwise to the rocket, and held thereto by an elastic band. A large number of them may be enclosed in a very small box or package. The bands or collars B on the rockets do not increase the dimensions of the same, so far as close packing is concerned.

In figs.- 2 and 4, a'modification of the invention is shown. In this instance the wings Q are permanently attached to the band or collar 13', and the latter is constructed of such dimensions that it may be fitted upon and removed from the rocket. The band is provided at its upper edge with a right-angular slot, e, intowhich a pin, on the rocket, enters, when the band or collar is shoved upon it, the pin and slot constituting what is commonly termed a bayonet fastening, as shown clearly in fig. 2. In packing the rockets, the bands or collars, with wings attached, are placed in a separate compartment in the box.

Thus it will be seen that by this invention I retain all the advantages of the original improvement, and materially reduce the cost of manufacture, the wings being applied to the rocket at a much less cost than by the original mode.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The application of detachable wings to a sky-rocket, through the medium of a collar or band, arranged so that the wings may be detached from the collar or band, or the latter detached from the rocket, substantiallyas shown and described.
